摘要
首次在带有蒸发冷凝冷却系统的专利铸模中进行了铝合金试铸,并提取了直径为 62 毫米的圆柱形铸坯。结果表明,通过将冷凝器出水温度提高到 t = 60-80 °C,可将模具冷却水流速降低 2-3 倍。考虑到结晶器的初步加热和温度的实验值,对壁温的设计计算进行了调整。在两种浇注模式下对获得的工件表面状态进行分析。对模具的供热和散热以及坯皮厚度进行了计算和比较。
Experimental mold for obtaining continuously cast billets from high alloy steels and alloys
For the first time pilot castings of an aluminum alloy into a patented mold with an evaporative-condensation cooling system are carried out with extraction of the resulting cylindrical billet obtained with a diameter of 62 mm. It is shown that the flow rate of cooling water to a mold may be reduced by a factor of 2–3 by increasing the temperature of the water leaving the condenser to t = 60–80 °C. Adjustments are made to the design calculation of wall temperatures, taking into account preliminary heating of the crystallizer and experimental values of temperatures. The state of the surface of the workpieces obtained is analyzed in two pouring modes. Calculation and comparison of heat supplied to and removed from the mold, and thickness of a billet skin are performed.
